Title: Improvements in or relating to apparatus for displaying information about a plurality of television signals or television signal components
IPC: H04N17/02
Filed: 1966-12-15
Abstract: 1,101,849. Monitoring television signals. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 15 Dec., 1966 [18 Dec., 1965], No. 56207/66. Heading H4F. The Specification describes a system for sequentially monitoring a plurality n of television signals, wherein the repetition frequency of the monitored display is equal to the field frequency Fo of the signals, and not equal to Fo/n. The system shown monitors the red R, green G, and blue B, colour signals of a 50 frames/sec. 625 line, colour picture. Line and frame sync. signals 5 are fed to a pulse generator 8 to produce a frame sync. pulse 12 having a frame period To, and three staggered gating pulses 9, 10 and 11 each having a duration equal to the line duration T 1  and a period equal to 3T 1  and respectvely gating the three colour signals through a switch 6 in line sequential fashion to the vertical deflection plates of a C.R.T. 1. Each frame sync. pulse 12 starts a ramp voltage 16 having a period and duration To and an amplitude Vo such that when applied as a horizontally deflecting voltage to C.R.T. plates 5, the spot moves 1/3ofthe C.R.T.'s display area diameter (see Fig. 2b). The gating pulses are also fed to a generator 13 which produces the repetative stepped voltage 14 shown in Fig. 2c, having a voltage, equal to 0 when the R signal is applied to plates 4, equal to Vo when the G signal is applied to the plates 4 and equal to 2 Vo when the B signal is applied to the plates 4. The two voltages 14 and 16 are added at 17 to produce the horizontal deflection voltage shown at Fig. 2d. Thus, on the C.R.T. display Fig. 2a, each colour signal will be displayed on a respective third of the display area. During time 0 to T 1 , the R signal is displayed at point 1, Fig. 2a, as a vertical bar having a length representing the amplitude of the R signal. During time T 1  to 2T 1  the G signal is displayed at point 3, and during time 2T 1  to 3T 1  the B signal is displayed at point 5. During time 3T 1  to 4T 1  the R signal is again displayed but now at point 7 and represent the R signal at a line in the picture a little further down the frame. Thus the variations of the R, G and B signals through the picture frame are displayed substantially simultaneously with a repetition frequency of 50 c/s. Transistorized embodiments of means 8, 13 and 17 are given in Fig. 3 (not shown).

Abstract: 1286649 Oven Control; pilot lights HARPERWYMAN CO 2 Dec 1969 [17 Dec 1968] 58835/69 Headings F4T and F4F A gas oven control means 12 which controls the supply of gas to a standing pilot 22, a control pilot 20 and an oven burner 18, comprises a knob 54 having a range of operating positions, a normal off position in which only the standing pilot 22 is lit, and a further off position in which the standing pilot 22 also is extinguished. In the operating position gas is supplied from an inlet 14, via arcuate channels 56b and 98 in the confronting faces 76, 78 of a valve body 68 and a member 80 rotatable by the knob 54 respectively, to passageway 60a-60d, communicating with a chamber 58 from which gas passes via an opening 122 and passage 64 to a safety valve 28 controlled by a probe 32 sensing the flame at the control pilot 20. In reaching an operating position, knob 54 produces, by means of threads 136a, axial movement of a spindle 136 which has a ring 134 acting as pivot for a lever 129 acting through a second lever 130 on a disc 116. This movement of spindle 136 enables disc 116 to be lifted by a spring 146, uncovering the end of a passageway  62, Fig. 1, for supplying gas to the control pilot 20, which is ignited by the standing pilot 22 to act on the probe 32 to eventually open safety valve 28. An oven temperature probe 36 is connected to an expansible diaphragm 124 which acts on lever 129 to open and close the passegway 62 supplying gas to the control pilot 20, which, via the probe 32 causes safety valve 28 to open and close, thus regulating the temperature. An additional standing pilot 40 is normally supplied continuously with fuel through conduit 42 and may be used to ignite the top burners (not shown) of a gas range. The diaphragm 124 is also connected to a disc 120 which, as the diaphragm expands, throttles the gas supply to safety valve 28. An opening 66a, Fig. 3, in the valve body face 76 is connected by passages 66b, 66c and a line 26 to the standing pilot 22, and in the normal off position, as in all operating positions of knob 54, is connected to the gas supply via channels 56b and 98, Figs. 5, 6 (not shown). However in the additional off position, Fig. 7, the opening 66a is out of communication with channel 98. The two pilots 20, 22 may be combined, Fig. 8 (not shown), and have two rates of gas supply to produce a small standing flame and a larger control flame when the control pilot supply is open.

Abstract: 1431505 Isotopic enrichment UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 28 Dec 1973 [10 Jan 1973] 59966/73 Heading C1A The different isotopes of sulphur contained in a sulphur dioxide feed fluid are separated by contacting and reacting said sulphur dioxide feed fluid with a solution of sodium, potassium or ammonium hydroxide at a temperature of 20 to 100 C. to form the corresponding bisulphite enriched, and render the feed gas depleted, in the heavier isotopes of sulphur, contacting the bisulphite solution with sulphuric acid at a temperature of from 25 to 70 C. to form sulphur dioxide enriched, and an alkali metal bisulphite solution depleted, in said heavier isotopes of sulphur, reacting the alkali metal bisulphite with more alkali metal hydroxide at a temperature of 25 to 100 C. solution to form the corresponding sulphate, and subjecting the sulphate solution to electrodialysis so as to regenerate the hydroxide and the sulphuric acid. In the apparatus of the figure, sulphur dioxide feed gas enters via conduit 16 and is then fed via conduit 18, from which it enters reaction vessel 20, which has an appropriate filler 22 disposed therein to increase the surface area of the reactants contacting the sulphur dioxide. Alkali metal hydroxide solution is fed in through conduit 24 so as to contact the feed gas in reaction vessel 20 and the alkali metal bisulphite solution formed flows downward into a chemical exchange column or second reaction vessel 26, which contains a filler 28 similar to the filler 22, wherein it is further enriched in the heavier isotopes. The solution then passes through conduit 30 into distillation apparatus 32, wherein it reacts under reflux with sulphuric acid, which is fed into conduit 30 via conduit 46, to form sulphur dioxide enriched in said heavier isotopes, which is removed through conduit 48, and alkali metal bisulphate solution, which is removed via conduit 58 to mixing vessel 60. In mixing vessel 60 the solution removed from distillation apparatus 32 reacts with alkali metal hydroxide which is fed in through conduit 62, forming alkali metal sulphate solution, which is then removed via conduit 66 to an electrodialysis unit 13. Said conduit 66 introduces said alkali metal sulphate solution into a compartment 74 of said electrodialysis unit formed by the walls of container 68, an anion permeable membrane 70 and a cation permeable membrane 72. The battery 76 causes a current to flow between anode 78 and cathode 80, as a result of which alkali metal ions migrate from compartment 74 to compartment 84 through the cation permeable membrane, and sulphate ions migrate from compartment 74 to compartment 82 through the anion permeable membrane. Hydrogen is liberated at the cathode 80, and oxygen at the anode 78, so that alkali metal hydroxide is formed in compartment 84, whence it is removed through conduits 24 and 62, and sulphuric acid is formed in compartment 82, whence it is removed through conduit 46.
